Android Device Monitor does not provide GPU systrace information

I have followed the guide to the letter regarding getting a GPU systrace from my running oculus quest app.

The system trace is successful, but i don't get the GPU timeline, even though the GPU RenderStage checkbox is ticked. 

Can I get some help here? I'm getting terrible performance in an otherwise extremely simple app, and I'm trying to figure out the culprit, but I can't without the proper tools!
